Description

A kind of jet type thermal shrinkage packing machine

Technical field

The utility model relates to packaging facilities technical fields, and in particular to a kind of jet type thermal shrinkage packing machine.

Background technique

Jet type thermal shrinkage packing machine is, by heating, to make to receive using shrink film-wrapped outside product or package Contracting film shrunk wraps product or package, and the article after packaging can seal, is moisture-proof, is anti-pollution, and protect commodity from coming from External impact has certain resiliency, especially when packing fragile article, can prevent from dispersing when vessel are broken, sufficiently aobvious The appearance for showing article improves the sales exhibition of product, increases beautiful and sense of worth.In addition, the possibility that product is split, stolen can be lowered Property.

Existing jet type thermal shrinkage packing machine usually passes through first will manually need article to be packaged to carry out just packaging, I.e. by shrink film-wrapped in the outside of package, then the package after first packaging is transported at thermal shrinking package machine again Heat shrinkable package is carried out, since there is also gaps between the package and shrinkable film after progress just packaging, package is not close, Therefore during transportation by it is artificial stir it is logical produce can at the beginning of broken parts it is packaged.

Since existing jet type thermal shrinkage packing machine has a single function, only has thermal contraction function, need in use The object for wanting manual handling just to pack, in the handling process often because packaged there is also have the gap between shrinkable film And lead to shaking of the object in packaging film and be damaged, the object after being damaged needs to re-start just packaging again, and existing The first package mechanism manual operation process having is complicated, expends a large amount of manual labor, packaging efficiency seriously reduces.

Utility model content

It is had a single function for jet type thermal shrinkage packing machine in the prior art, manual operation process is complicated, hand labor is strong The problem that degree is big, packaging efficiency is extremely low, proposes a kind of jet type thermal shrinkage packing machine, the jet-propelled thermal contraction of the application Packing machine have it is multi-functional, easy to operate, labor intensity is low, the high advantage of packaging efficiency.

To achieve the goals above, the utility model provides a kind of jet type thermal shrinkage packing machine, including support frame, described It is connected with thermal jet mechanism of qi structure on support frame, just package mechanism, just package mechanism and the heat are connected on support frame as described above By connection transmission mechanism connection between jet mechanism, the just package mechanism includes the inclination pan feeding of connection on the support frame Plate, the inclination feeding plate are separately provided for the first roller bearing and the second roller bearing of winding shrink film, first rolling up and down Axis connection has driving mechanism one, and driving mechanism two is connected on second roller bearing, offers and is used on the inclination feeding plate The through-hole that shrink film passes through, the side close to the through-hole of the transmission mechanism are provided with packaging mechanism.

The working principle and process of the technical program are as follows: articles to be packaged will be needed to be placed into first and cut oblique flitch On, object slides down from inclination feeding plate, by the shrink film connected between the first roller bearing and the second roller bearing, passes through driving Mechanism one drives the rotation of the first roller bearing, and driving mechanism two drives the rotation of the second roller bearing, wherein the frequency of the first roller bearing rotation is greater than The frequency of second roller bearing rotation, needs articles to be packaged to move down by the gravity of itself, by through-hole, to make package Upper winding shrink film, package pass through after packaging mechanism, and the shrink film that packaging mechanism is wound carries out hot melt encapsulation, is sealing Object surface is wrapped up in shrink film side at dress, and the other side is similarly formed a strip hot melt mouth, is only needed at this time through driving mechanism two It drives the rotation of the second roller bearing that the shrink film containing hot melt mouth can be wound up on the second roller bearing, avoids on next package Often have strip hot melt sealing and influence whole aesthetics, the object surface after hot melt encapsulation covers one layer of contraction Film, there is also gaps between object and shrink film at this time, can be led to by being conveyed into thermal jet mechanism of qi structure for transmission mechanism Crossing heating shrinks shrink film, so that it be made to wrap with packaged.Wherein driving mechanism two is motor.
